What you saw was a post-64 Winchester 94 commemorative Rifle, which were made with 26" octagonal barrels. (The Carbine versions had 20" bbls)
There were only three Winchester .30-30 commemoratives, that were made with Gold-plated, or brass-plated, receivers & 26" octagonal bbls.
They were:
1966: Winchester 66 Centennial
1970: Lone Star Commemorative
1970: North West Territories Deluxe (Canadian), w /24" bbl
While many other Model 94 commemoratives also had gold-plated receivers, they all had either 20" barrels, or were not chambered in .30-30.
While many other Model 94 commemoratives also had 26" octagonal barrels, they did not have gold-plated (yellow) receivers.
